In Germany July 1, 1933 f ThisV invention relates to an adjustable fastener for belts, garments, bags or the like. More particularly the invention refers to that type of fastener, in which there are provided on the one 5 part of the article to be secured a series of catches or abutments, over which there is passed a slidelike locking member se'cured to the second part of the said article.

Heretofore it has beenusual to employ for the catches smooth pieces of wire or sheet metal on a flexible supporting band. These pieces of wire or sheet metal are preferably clamped to the folded middle portion of the band.

The known catches or abutments reveal vari- For example, they do not permit suiiiciently firm engagement on the part of the slide member, so that when even a relatively slight pull is exerted on the fastener the slide member will be withdrawn from the catches and the fastener accordingly released. This disadvantage will be found to exist both when the pieces of wire or metal are clamped to the folded middle portion of the supporting band -as well as when the same are secured to the said band in immediate fashion, since in either case the pieces of wire or sheet metal do not project a sufficient extent away from the surface of the band to provide a sufcient hold for the slide.

Further in the majority of cases it is necessary to employ for the wire or metal members a special supporting member, which in turn requires to be amxed to the article concerned, unless the parts are produced on the article during th'e manufacture itself, as in the case of a -lightning fastener.

It is the object of the invention to overcome the disadvantages associated with the known forms of embodiment, and this is accomplished by making the catches in the form of mushroom 40 headed studs forming guide means for a slidable means for the buckle, the latter need not engage the edges of thebelt or other article whereby wear of said edges is prevented.

The fastener according yto the invention may be employed for an extremely large number of articles.

The invention will now be described more fully with reference to the accompanying drawing, in which Fig. 1 is a perspective view showing the fastener secured to a belt. 5

Fig. 2 is a plan view of the fastener.

Fig.- 3 is a longitudinal section through the same, and

Figs. 4, 5 and v6 illustrate different forms of the stud-like catches. 10

To the belt l there are secured, onebehind the other, a. series of headed stud-like catches spaced a suitable distance apart. The studs 2 possess a neck portion 2', and may be secured to the belt l, for example, by folding over the l5 extensions 2". y

The belt I is secured with the assistance of the slide-like buckle 3. The lower part d of the slide 3 possesses a guide 5 corresponding with the cross-sectional form of the headed studs 2, 20 so that the slide 3 embraces the necks 2' of the studs 2.

Within the slide there is located a spring 6, which is bent over at the 'front end 6' to form a nose capable of engaging in the space between 25 two studs 2. The opposite end of the spring 6 is secured to a plate l possessing a bulged portion 9 adapted tosupport the spring 6. The same is moved by a slide button 8.

'I'he slide 3 is secured by a keeper I0 to the 30 opposite end of the belt .I. To permit numerous possibilities of fastening or adjusting the belt'l there may be provided any desired number Iof studs 2. Thev slide or buckle 3 is passed over the studs 2, and is locked 35 in position at any point where studs may be provided when, by means. of the button 8, the end 6' of the spring 6 is moved into the space be- -tween two studs. To open the fastener the butm ton 8 is moved into the position of rest shown 40 in Fig. 3 in broken lines. The tensioning of the spring 6 takes'place over the bulge 9. In the position of the button 8 indicatedin broken lines the slide 3 is able to pass freely over the studs 2.

The stud 2 may be made in various forms. In 45 Fig. 4, for example, the same possesses a rounded head. In Fig. 5 the stud is made in the form of a rivet Il, the upper portion Il' ofwhich may be covered with textile or any other material.

The head may also be composed of articial resin 50 or other colored material, and in fact the studs,

if desired, may be adaptedv in their appearance to the particular article to which they are secured.-

In Fig. 6 the stud possesses a head l2 of greatly rounded form. 55

What I claim as new and desire to secure by Letters Patent is:

1. Adjustable buckle fastening for belts, garments, pouches, and like articles comprising a row of studs mounted on one end of the belt and each stud having head and neck portions, a slide mounted on the other end of the belt and guided on the studs over the heads and emmounted on the other end of the belt and being adapted to pass over the heads and embrace the necks of a plurality of said studs, whereby said slide is guided on the studs, and means cooperating with the studs for releasably locking the slide against any desired stud.

3. Adjustable buckle fastening for belts, garments, pouches, and like articles comprising a row of studs mounted on onev end of the belt and each having head and neck portions, a slide mounted on the other end of the belt and guided on the studs by passing over the heads and embracing the necks of a plurality of said studs, and means cooperating With'the studs for releasably locking the slide against any desired stud, said means including a spring in the slide having a nose capable of entering spaces between the studs and a button movable between locking and unlocking positions, said button in its locking position positively holding the nose of the spring in one of said spaces and in its unlocking position permitting said'nose to ride over the studs.
